先附上我在Github上存放的代码仓库: The Python Challenge
依然是先查看网页源代码。发现有个链接’…nothing=12345’
点进去之后发现又给我们一个数字，引导我们去下一个链接，于是可以知道，只要链接爬到了终点，那么就会出现别的提示信息
果然，爬到终点之后，提示我们除以二，继续爬，所以只要把代码改个数字就好，我的代码如下：
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
| #!/usr/bin/env python3
# -*- coding: utf-8 -*-
__author__ = 'Yuuki_Dach'
from urllib import request
import re
mainUrl = 'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing='
subUrl = '8022' # first try is '12345'
subUrl2 = ''
i = 400
while subUrl != subUrl2:
subUrl2 = subUrl
pyUrl = mainUrl + subUrl
req = request.Request(pyUrl)
resp = request.urlopen(req)
urlContent = resp.read()
pattern = re.compile(b'\d+', re.S)
contents = re.findall(pattern, urlContent)
for content in contents:
subUrl = content.decode("ascii")
print(subUrl)

最后得到’peak’。只不过注意后缀要改回’.html’就行了
